Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety during repairs.
Raise the vehicle and secure it on jack stands if necessary.

2. Replace Power Steering Fluid

Tools Required: Fluid extraction pump, new power steering fluid (check specifications in the owner's manual).
Use the fluid extraction pump to remove old power steering fluid from the reservoir.
Fill the reservoir with new power steering fluid until the correct level is reached.

3. Inspect and Replace Steering Angle Sensor

Tools Required: Socket set, multimeter.
Remove the steering column covers to access the steering angle sensor.
Disconnect the sensor connector and remove the mounting screws.
Using the multimeter, test the sensor for proper voltage output.
If faulty, install a new steering angle sensor by reversing the removal steps.

4. Inspect and Replace Power Steering Pump (if necessary)

Tools Required: Socket set, fluid catch pan, new power steering pump.
Locate the power steering pump; remove any components obstructing access (e.g., belts, brackets).
Disconnect the pump’s inlet and outlet hoses, allowing any fluid to drain into the catch pan.
Remove the mounting bolts and take out the old pump.
Install the new pump, ensuring all hoses are securely attached, and refill the power steering fluid.

5. Reconnect Battery and Test

Reconnect the vehicle battery.
Start the engine and turn the steering wheel from lock to lock to bleed the system of air.
Check for any leaks around the pump and hoses.
